Thermostat and housing

This is what was on the intake with no thermostat. It came with a o-ring and no recess for a thermostat.
Is there a Motorad style with the t-stat recess like the 4830kt housing but with the neck at this angle so I don't have to buy a new top radiator hose?
Most pics on the internet don't show the mounting face. or dimensions.
